This inventionrelates to improvements in paper clips, and moreparticularly to clips which are formed by bending a continuous wire intoopen loops, two of which 100 s extend in the same direction and havetheir ends spaced a com aratively short distance apart, said loops ingcapable of being spread apart laterally of the clip thereby,

rangement of parts shown in the drawings,

wherein Fig. 1 represents a plan view of a portion of one or more sheetsof paper having one of my cli s applied thereto; Fig. 2 a plan view andig. 3 a sideelevation of the said clip; Fig. 4 a side elevation of theclip and paper shown in Fig. 1.

Referring to the form of my invention shown in Figs. 1 to 4 inclusive,the clip as a whole comprises a resilient wire having the portions 1, 2,3, 4, 5, 6, 7, 8, 9 and 10.

The portions 1, 2 and 3 are so bent as to provide a pair of converginglegs 1 and 3 and a connecting member 2 for the divergent ends of saidlegs, the said parts forming an open loop having the part 2 deflectedupwardly and above the plane of the parts 1 and 3 forming a hump. Thelegs 3 and 5 are connected at their convergent ends by a narrow bend 4forming a second open loop extending in the opposite direction from thefirst loop. The wire of which the clip is formed is further bent at 5, 6and 7 to form a third open loop which is wider than the first loop andwhich encloses the widened art of such first loop. The part 6 of thisthir loop is bent downwardly and out of the plane of the parts 1, 3, 5and 7, to form a hump projecting in the opposite direction from the hump2, the said humps projecting transversely of the plane of the clip. Thepart 7 is bent upon itself at 8, forming a bar orvle 9 which ispreferably parallel with the leg and the end of which 1s bent atsubstantially right angles to provide a sharp point or pin 10 ofsuflicient length to extend throu h several sheets of pa er. .The parts8 an 9 constitute a loop which is located outside of the loops 2, 4 and6.

The clip is applied to two or more sheets of paper b springing theperts2 and 6 apart, so t at the downwardly projecting hump 6 will engagethe top of the upper most sheet while the upwardly projecting loop orhump 2 will engage the underside of the bottom sheet,-thus clamping thesheets between the humps 2 and 6 on the jaws provided by the closed endsof the loops.' By bending the sheets 11 and 12 downwardly on that sideof a clip which carries the arm 9 and pm 10, as the clip is beingslipped over the sheets, the point 01 pin 10 can he slipped along'thetop sheet without difliculty,

after which it can be pressed through the sheets by straightening up thelatter and pressing down upon the arm or leg 9.

With this construction of clip, the sheets will be clamped securelybetween the oppos1te1y extending humps on the jaws formed by the closedends 2 and 6 of thecorresponding loops, thus enabling the clip to clampthe sheets firmly and also to prevent the accidental insertion of sheetsbetween said humps or loop ends and the sheets which are securedtogether thereby. Furthermore, as the point or projection 10 extends atright angles to the body of the clip, it will secure the sheets togetherin the manner of a pin and thus prevent their unintentional removal fromthe clip. I

When it is desired to remove the clip, the paper on the side thereofwhich carries the pin or point 10 may be bent downwardly to disengage itfrom such point and the parts 2 and 6 may be then separated a sufficient"distance to enable the sheets to be removed.

Reference has been made hereinbefore to the divergence of the wires 1and 3, 5 and '8' toward the ends or humps 2 and -6 of their respectiveloops and to the convergence of the legs 3 and 5 toward the end 4 of theoppositely extending loop. This enables me te secure a firmer grippingenga ement between the legs 1, 3, 5 and 7 an the paper interposedbetween the gripping loops than if a clip of the ordinary shape wereemployed. Unless the sheets to which the clip is applied areparticularly stifi, the humps 2 and 6 will bend the paper in oppositedirections, enabling the legs of the clamping loops to engage oppositesides of the sheets.

In Fig. 4, for clearness of illustration the legs forming the sides ofthe clamping loops are shown as spaced from the sheets 11 and 12. Inpractice, however, unless the sheets be particularly stifi, these legswill engage the sheets and will provide a firmer gripping engagementwith said sheets, even without the hum s 2 and 6, than can be socured bythe or inary clip. v

Having thus described my invention, what I claim is 1. A paper clipconsisting of a continuous wire bent to form an outer loop and an innerloop continuous therewith, the said loops extending in the samedirection and being connected by a loop extending in the oppositedirection, the wire forming one side of the outer loop being bent uponitself to form a loop outside of said loops and the extreme end of suchwire being bent at substantially a right angle to the plane of the clipand providing a projection of suflieient length to be inserted throughseveral sheets er.

of palp 2. paper clip consisting'of a continuous 2 Wire bent to form anouter loop and an inher loop continuous therewith, the said loopsextending in. the same direction and being connected by a loop extendingin the opposite direction, the wire forming one side of the outer loopbeing bent upon itself to form a loop beside said loops and the extremeend of such wire being bent at substantially right angles to the planeof the clip and providing a projection of sufiicient length to beinserted through several sheets of paper and the ends of the outer andinner loops being deflected in opposite directions transversely of the(plane of the cli to provide humps adapte firmly therebetween.

In testimony whereof, I hereunto afix my signature.
